Physics · Current Electricity
According to Kirchhoff's Current Law (KCL), if currents entering a node are assigned a positive sign and currents leaving are assigned a negative sign, which of the following node relationships is/are universally correct for any electrical network junction? I. At node 'a': Current entering equals current leaving (e.g., i1 + i4 = i2) II. At node 'c': Current entering equals current leaving (e.g., i3 = i6 + i7) III. At node 'b': Current entering equals current leaving (e.g., i2 + i5 = i3)
